Work it out the circumfrance of a circle is pie x the diameter!
circumference = 2*pi*5
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
Formula to find the circumfrance of a circle~(2)(3.14)r or (3.14)d
the circumference of a circle is the length around the outer edge. and you find it by using the formula 2 times pi times the radius of the circle
it is the circumfrance of a circle divided by pi.
If the circumference (not circumfrance) is 31.4, the radius is 4.9975 units (to 4 dp).

The diameter should be 7m.

Work it out the circumfrance of a circle is pie x the diameter!
circumference = 2*pi*5
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
multiply the radius by two then pultiply that by pi
In any circle, the ratio of circumference to diameter is (pi).
